The older we get, the more our fibrin levels fluctuate. Fibrin is an important protein involved in blood clotting.

Nattovena contains one of the highest fibrinolytic activities per capsule of any pure nattokinase supplements. This unmatched activity makes Nattovena a great choice for supporting normal blood viscosity and a healthy cardiovascular system.

Nattovena is one of the strongest nattokinase supplements available, period. It provides more than 4,000 fibrinolytic units (FUs) per capsule, which is twice the potency of ordinary nattokinase products. Plus, it’s naturally acid-stable since it’s derived from a food source. This gives Nattovena the added benefit of not needing an enteric coating for protection against stomach acid.

Nattokinase is a fibrinolytic (fibrin-dissolving) enzyme originally discovered in a Japanese fermented soybean food called natto. This soybean dish is fermented with a strain of Bacillus subtilis bacteria that in turn produces the nattokinase enzyme, which upon its discovery was later named after the respective dish. The fermented dish, natto, has a slimy texture, sour taste, and strong smell that is very unappealing to some.

Despite its questionable taste, natto has been shown in numerous studies to have many health benefits. For its use in nutritional supplements, the nattokinase enzyme is extracted and purified in a lab, so the benefits of the enzyme can be had without disrupting your palate.

How Nattokinase Works

Fibrin is a protein that plays a major role in blood clotting and scar formation, making it an essential component of the healing process—and vital for maintaining your health and general well-being. However, fibrin overproduction and weak fibrin degradation have been a factor in many of today’s most common circulatory health concerns.

Fibrin is naturally produced in the body by a protein called thrombin and broken down by the body's own fibrinolytic enzyme, plasmin. Fibrin is typically produced during the recovery and healing processes that are triggered by an injury or other health concerns. Usually, the production of fibrin occurs in a delicate balance. However, many conditions can impair fibrin degradation and lead to excessive levels of fibrin within the body.

Nattokinase is a fibrinolytic enzyme in and of itself, which means that it dissolves excess fibrin during the healing process. In fact, studies show that nattokinase is actually more potent than the body’s own plasmin in terms of breaking up blood clots—a process which is referred to as thrombolytic therapy or fibrinolytic activity.

Nattovena is an ultra-concentrated 4,000 FU pure nattokinase dietary supplement, in easy-to-swallow capsules.

Nattovena's potency is unparalleled in its class. The standard for nattokinase manufacturing is a potency of up to 2,000 FUs, or fibrinolytic units, of fibrin degrading activity per capsule. Nattovena has broken the mold by providing 4,000 FUs of activity—double the ordinary dose—making it the strongest nattokinase activity per capsule in its class, period.



A fibrinolytic enzyme that helps to maintain normal blood viscosity and support cardiovascular health. The enzyme was discovered while studying the fermented soy dish known as “natto.” A researcher was trying to uncover why certain foods had higher fibrinolytic activity than others. He came upon a Japanese fermented soybean food called natto that had large volumes of an enzyme that he coined “nattokinase”, based on where he discovered the enzyme. He later found that a microorganism that was used in the fermentation process was responsible for creating this enzyme. This same microorganism (Bacillus subtilis) is used today in the production of the enzyme.

Suggested Use

Directions: Take Nattovena with eight ounces of water on an empty stomach or as directed by your healthcare provider. Higher daily doses may be divided into two or three servings per day.

Maintenance: Two capsules per day. Increased Support: Four capsules per day. Therapeutic: Six capsules per day.

Warning: Do not take this product without the consent of your physician if you are currently taking blood-thinning medications or if you are pregnant or nursing.


What does Nattovena do?

Studies have demonstrated that nattokinase improves overall circulation, promotes healthy blood viscosity, and maintains healthy blood levels.

Why is fibrinolytic activity important?

Fibrin is a vital protein that forms in response to trauma, injury, or even in cases of autoimmune conditions. The body not only has the potential to overproduce fibrin in response to these instances, but can also produce fibrin when no trauma or injury has occurred, which can lead to a bevy of unwanted symptoms. Fibrinolytic activity is important because it’s the body’s natural way of breaking up excessive fibrin.

Is Nattovena safe?

Nattokinase is derived from natto, which has been a regular food staple in Asian cuisine for centuries. Although nattokinase has many benefits, studies have shown that it also does not have demonstrative side effects, and the ingredient is considered GRAS (generally recognized as safe) in the US.

Does Nattovena have value beyond just heart health?

Due to the vast array of unhealthy conditions that excessive fibrin can bring, Nattovena has far greater value than a simple cardiovascular support product. Many aspects of health, ranging from muscle recovery to immune health, can be related to fibrin and blood viscosity.

Is Nattovena safe to use in combination with prescription blood-thinning medications?

You should always check with your healthcare provider prior to taking any new dietary supplements in combination with a prescription. However, Nattovena does not contain any vitamin K, so it is assumed to be compatible with prescription medications with a mode of action based on inhibiting vitamin K. Nattovena is not contraindicated with aspirin, natural supplements, or antihypertensive medications, although medical supervision when implementing any new supplement regimen is always recommended.

Is Nattovena Kosher?

The formula is Kosher, and a copy of the certification is available by request .

Is Nattovena vegetarian or vegan?

The formula is vegetarian and vegan in accordance with the guidelines of the AMERICAN VEGETARIAN ASSOCIATION.

The Best Nattokinase
My doctor suggested I take Nattokinase enzymes to support my heart. He recommended Natto NSK, but I had to take 4 pills everyday. I found Nattovena pure Nattokinase was double the strength. Who would ever want to take baby aspirin again?

Nattovena And Serretia
I have been taking Nattovena and Serretia together for a month and a half to support fibrin in my uterus. I can tell is working because my stomach is visibly flatter and my waste size has gone down an inch and a half! I also notice that my athletic recovery time is less then it used to be.

I am taking Nattovena twice daily. I have heart issues and do not wanted something natural. so I take this product in the hope that it is helping to improve blood viscosity. I have been taking it for several months. I live in England and am pleased with the ease of ordering the product from the company and am very happy that it arrives quickly.

Great for seniors!
After heart attack 2 years ago, my father started to use nattokinase with other supplements. Today those supplements are only pills that he is taking, because he doesn't need anything else.

Enhanced circulation
I have been using Nattovena, pure nattokinase, for over a year and a half. In addition, I take Neprinol AFD with Nattovena. Both products are outstanding and I have benefitted from them as my blood test results have shown. I have noticed that the spider veins on my right foot area have mostly all disappeared since using Nattovena. I would recommend these products to anyone interested in improving their blood circulation.

Nattovena to the rescue!
After suffering circulation issues multiple times in my calves and 7 years of taking meds, my overall health began to deteriorate. I felt sluggish, constantly tired even after a full night of sleep and quite frankly easily depressed. Within a day of taking Nattovena I began to breath easier, within a week my long and short term memory gradually improved, instead of four hours I could be active for sixteen -with no naps! Greatest of all : a sense of well being and hope returned to my life as I was able to take control of it again. After 5 years, I am finally back to training in the gym and couldn't be happier. After doing some research, I may jump to Neprinol and possibly Serretia with my doctors consent and reduce BIG PHARMA pills as it hinders my cognitive abilities and sense of well being - I've felt sharper without it. In any case, I sincerely hope this product will help you in your own struggle for renewed health and increased freedom. James Valderhaug.

I switched to taking only Nattovena
I have been taking nattokinase for several years. After surgery a couple years ago,( for circulation), my cardiologist insisted I take a very blood meds. I told him I would not and that I would continue taking only the nattokinase. At that time I switched to taking only Nattovena, two capsules a day, one in morning and one in the evening. I have had no problems and I do not expect to. Nattovena from Arthur Andrew is as good as it gets! Thank you

Not the right product, but not your fault.
Can't tell that it made any difference. Maybe this product is not what I need to address my health problems. I thought maybe my knee swelling and pain was caused by a blod clot. But I saw an othopedic doctor and it turns out that I have psuedogout, a meniscus tear and arthritis. So nattovena was not the right answer. I'm sure it's great for other problems. Thank you for the good service and the reasonable price.

So strong and what a deal!
I have been taking 16,000 fu's of nattokinase daily for years. The only way to do this was to take 8 capsules a day. Nattovena allows me to take this same dose, but I only have to take 2 caps twice a day, so much easier. Nattovena is also the best priced nattokinase I have been able to find. Thank you.
